摘要
为研究轮履变换车辆主动轮与履带板啮合的损耗变化,首先结合轮履变换车辆结构,对其进行受力分析;然后采用Matlab和Recur Dyn建立了主动轮与履带板啮合数学模型和多体动力学仿真模型;最后,仿真分析了该车辆在轮式状态和履带状态下,分别在硬质路面上以10 km/h、20 km/h、30 km/h、40 km/h、50 km/h匀速行驶一段时间内的主动轮与履带板啮合的功率损耗,结果表明,该车辆在轮式状态下匀速行驶时,其主动轮与履带板啮合的功率损耗低于履带状态,特别是在轮式状态下以40 km/h匀速行驶时,其主动轮与履带板啮合的功率损耗比在履带状态下匀速行驶时减少了36.49%.
In order to research the transformation of sprocket mesh power loss of wheel-tracked vehicle, loads analysis combined with wheel-tracked vehicle structure was conducted at first. Then mathematical models of sprocket and track were built. Multi-body dynamics simulation of wheel-tracked vehicle was conducted based on Matlab and RecurDyn. Finally, dynamic transformation of sprocket mesh power loss in the invariable speed process on hard road was analyzedat the speed of 10 km/h, 20 km/h, 30 krn/h, 40 km/h and 50 km/h. The result indicated that the wheel state of wheel-tracked vehicle decreased the sprocket mesh power loss efficiently. Especially at the speed of 40 km/h, sprocket and track mesh power loss of wheel state is 36.49% less than that of track state.
